Properly pickled mushrooms retain their beneficial properties and last longer. The marinade gives neutral-tasting mushrooms a spicy aroma, sourness and pungency. Pickled mushrooms are a dietary product, a source of unique protein compounds and microelements. They improve the functioning of the cardiovascular system and prevent cancer. More often they are served as a separate cold appetizer, but there are recipes where they are especially good hot. Among them is toast with pickled mushrooms.
